INSPECT SEAT HEATER CONTROL SUB-ASSEMBLY (for Front Side)

Disconnect the c13 and c1 heater control connectors.

Measure the resistance according to the value(s) in the table below.

• Standard Resistance:

• for LH Side

  Tester Connection	Specified Condition
  c13-6 (E) - Body ground	Below 1 Ω

• for RH Side

  Tester Connection	Specified Condition
  c1-6 (E) - Body ground	Below 1 Ω

If the result is not as specified, there may be a malfunction on the wire harness side.

Measure the voltage according to the value(s) in the table below.

• Standard Voltage:

• for LH Side

  Tester Connection	Switch Condition	Specified Condition
  c13-1 (SWL) - c13-6 (E)	Engine switch on (IG), seat heater switch off	Below 1 V
  	Engine switch on (IG), seat heater switch on	11 to 14 V
  c13-4 (B) - c13-6 (E)	Engine switch off	Below 1 V
  	Engine switch on (IG)	11 to 14 V

• for RH Side

  Tester Connection	Switch Condition	Specified Condition
  c1-1 (SWR) - c1-6 (E)	Engine switch on (IG), seat heater switch off	Below 1 V
  	Engine switch on (IG), seat heater switch on	11 to 14 V
  c1-4 (B1) - c1-6 (E)	Engine switch off	Below 1 V
  	Engine switch on (IG)	11 to 14 V

If the result is not as specified, there may be a malfunction on the wire harness side.

Connect the c13 and c1 heater control connectors.

Measure the voltage according to the value(s) in the table below.

• Standard Voltage:

• for LH Side

  Tester Connection	Switch Condition	Specified Condition
  c13-5 (THL) - Body ground	Engine switch on (IG), seat heater switch on, volume Min→ Max	Gradual increase from below 1 V to 11 to 14 V

• for RH Side

  Tester Connection	Switch Condition	Specified Condition
  c1-5 (THR) - Body ground	Engine switch on (IG), seat heater switch on, volume Min → Max	Gradual increase from below 1 V to 11 to 14 V

If the result is not as specified, the seat heater control may have a malfunction.
